Patagonia's most versatile synthetic baselayer keeps you dry and warm. The sky may be blue, but the air high on Yerupaja's face doesn't exactly feel like spring. Made of Capilene® 3 Midweight, our most versatile and fastest wicking performance baselayer, these bottoms are designed to manage the extremes of high-output exertion in cool to cold conditions, and provide excellent insulation and ultimate comfort next to the skin. Brushed on the inside for warmth, Capilene 3 is soft and compressible, and the smooth jersey exterior glides smoothly under layers. Details include a comfortable brushed-elastic waistband and a gusseted crotch for extra mobility. Made of a 5.4-oz Polartec® Power Dry® polyester (65% recycled) double knit with Gladiodor® odor control for the garment. Recyclable through the Common Threads Recycling Program.
